Why most people fail

Diets don't fail people.
Diets fail to fit them.

  • Generic plans ignore your protein target.
  • Static plans don't survive a busy week.
  • The scale stalls and no one tells you why.
  • You hit goal weight and the app has nothing left to say.

We build a plan that adapts to you — not the other way around.

Plans on demand. Built around you.

Ask for a 7-day meal plan. Adjust on the fly. We design around your goal, schedule, and favorite foods — and adapt as you go. Vegetarian, low-carb, GLP-1-friendly, family-meal-friendly — we adjust the inputs, not your life.

Gentle nudges, not nagging.

A check-in before lunch. A note if you've gone quiet. Nothing pushy — just a friend keeping you on track.

Always there. 24/7.

9pm cravings, restaurant menus at lunch, hard mornings. The consistency layer that makes everything else stick.

Movement that fits your day.

Walks, weights, or whatever you actually enjoy. We build the workout around your time, energy, and goal.

We remember everything.

Allergies, slip-ups, last week's wins, what motivates you. The conversation gets smarter every time you text.

could look like.

Questions

Things people often ask.

What is NanoRhino?
NanoRhino is an AI weight loss coach you text. Think of it as a personal AI nutritionist, AI dietitian, and AI calorie counter rolled into one — sent to you over SMS at (915) 277-7888. No app required. It provides personalized coaching, daily check-ins, photo-based meal logging, and emotional support throughout your weight-loss journey. You only pay $10 per pound you actually lose.
How do I get started?
Go to nanorhino.com/message and pick a channel. SMS is live in the US now — text START to (915) 277-7888 and the AI replies in seconds, no app or account needed. WhatsApp, iMessage, and Telegram are coming soon; drop your email on /message and we'll let you know the moment your channel goes live.
Do I need to download an app?
No. SMS is the primary way to use NanoRhino — it lives in your Messages app. We also offer an optional iOS app for users who prefer it, but it's not required.
I'm on a GLP-1 (Ozempic, Mounjaro, Wegovy, Zepbound) — does NanoRhino fit?
Yes. About 20% of our active users are on a GLP-1. NanoRhino is built to complement the medication, not duplicate it: the coach focuses on hitting protein (so you protect muscle on a suppressed appetite), staying hydrated, and adjusting calories as your weight comes down through dose changes. We don't medicate, prescribe, or give medical advice — your doctor stays in charge of dosing. We just help you eat well within whatever appetite you have on any given day.
I'm at my goal weight — can NanoRhino help with recomp or maintenance?
Yes. The coach can run a recomp plan (losing fat while building muscle through a small deficit + protein + resistance training), a strict maintenance plan, or a lean-gain plan. Just tell us what you're after when you start; the meal plans, protein targets, and weekly check-ins adapt. Pricing only applies if your goal is weight loss — recomp and maintenance clients don't pay the per-pound fee.
How does pay-for-results pricing work?
NanoRhino charges $10 per pound you lose, capped at $500 total. If you don't lose weight, you don't pay. This aligns our incentives with your success — we only succeed when you do.
Is NanoRhino a free AI weight loss coach?
Texting NanoRhino is free for up to 50 messages per day, and you only pay if you actually lose weight — $10 per pound, capped at $500 total. There's no subscription, no upfront fee, and no charge if the weight doesn't come off. So functionally it's a free AI weight loss coach until you get results, then it's a results-based fee.
Is there a message limit? What does it cost to text?
NanoRhino SMS coaching is free for up to 50 messages per day. Standard carrier message and data rates may apply. If you exceed your daily free allowance, additional usage fees may apply — we'll always notify you before any charge.
Is NanoRhino private and secure?
Yes. NanoRhino is a private, judgment-free space — your conversations live in your Messages app. There are no social feeds, no posting, and no sharing. Your health data is encrypted, never sold, never shared with third parties, and never used for advertising. You can request deletion of all your data at any time.
How is NanoRhino different from other weight-loss tools?
Most apps make you tap through screens to log calories or follow generic meal plans. NanoRhino is a conversation: text a meal photo and get a calorie estimate back; vent about a hard day and get coached through it. It's like having a private nutrition coach on speed dial — at a fraction of the cost.
How is NanoRhino different from ChatGPT or other general AI assistants?
Three reasons. First, NanoRhino remembers everything you've told it — goals, allergies, last week's wins, your hard days. ChatGPT loses that context across conversations. Second, NanoRhino does the math reliably — calorie counts, macro targets, weekly weight-loss math — without the arithmetic slips a general model makes. Third, NanoRhino is purpose-tuned to be a non-judgmental coach. A general AI tries to be helpful, but it isn't designed to meet you consistently in cravings, shame, or setbacks the way a real coach should.
I've tried calorie counting before and it didn't work. Why would this?
Because the coach is what was missing, not the math. Most apps hand you a number and walk away — when you stall, when life gets in the way, when you don't know what to eat, you're on your own. NanoRhino handles the daily questions: what to eat that hits your protein, why the scale moved or didn't this week, how to handle a wedding or a hard week. The calorie math is automatic; the coaching is the product.
